CHILL.

SPECIFICATION forming part of Letters Patent No. 532,888, dated January22, 1895.

Application filed July 9, 1894.

To all whom it may concern:

- Be it known that I, JOHN MATHEUS, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee, and in the State ofWisconsin, have invented certain new and useful Improvements in Chills;and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention has for its object to prevent formation of soft spots insuch castings as are hardened by running water through a hollow chill;and it consists in certain peculiarities of construction and combinationof parts whereby water may be run into the chill through a plurality ofinlets, diverted in opposite directions from each inlet and dischargedthrough a plurality of outlets; as hereinafter more fully set forth withreference to the accompanying drawings and subsequently claimed.

In the drawings: Figurel represents a transverse section on line 1-l ofthe succeeding figure and illustrates a car-wheel chill embodying myimprovements. Fig. 2 represents a plan View of the chill partly inhorizontal section.

Referring by letter to the drawings A represents a car wheel chill ofordinary construction, except that the same has a vertical outer wallthereof provided with two lateral inlet nipples B diametrically oppositeeach other and two lateral nozzles C also diametrically opposite eachother intermediate of the nipples, the latter and the nozzles being soconstructed as to engage with hose-pipe couplings D of any suitablepattern. Within the hollow portion of the chill another vertical wall isprovided with preferably triangular projections E opposite the nipplesand these projections divert the inflow of water thereby causing thesame to' travel in opposite directions toward the nozzles, said waterbeing supplied to both nipples through branches F of a common hose G orother suitable conveyers for water under pressure.

The hose H joined to each of the nozzles conveys the waste water to anyconvenient point. Y

As is usual in the art, the chill is made hot,

by steam admitted and discharged through the hose connections to thusprovide against Serial No. 516,981. (No model.)

fracture of said chill when the metal is poured, and afterthis heatingthe water is turned on during the pouring operation.

From the foregoing it will be seen that the water entering each nippleis divided into two currents flowing in opposite directions to thenozzles, and there being a plurality of nipples and nozzles the travelof any current of said water within the chill is quite limited, wherebyI am enabled to keep said currents at a comparatively low temperatureand thus prevent conversion of the aforesaid water into steam, suchconversion in ordinary chills being productive of soft spots in thecasting.

It is obvious that the structural details herein set forth may besomewhat varied without departure from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A hollow chill having a vertical outer wall provided witha pluralityof lateral nipples for connection with a water-supply system, aplurality of lateral nozzles leading from said wall intermediate of thenipples, and cu rrent-diverting projections on an inner vertical wall ofthe chill opposite said nipples, substantially as set forth.

2. A hollow chill having a vertical outer wall provided with a pluralityof lateral inlets for water under pressure, a plurality of lateraloutlets in said wall intermediate of the inlets, and triangular currentdiverting projections on a verticalinner wall of the chill opposite saidinlets, substantially as set forth.

3. A hollow chill having a vertical outer wall provided with a pluralityof lateral inlets for water under pressure,-a plurality of lateraloutlets in said wall intermediate of the inlets, and current divertingprojections on a vertical inner wall of the chill opposite said inlets,substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee andState of Wisconsin, in thepresence of two witnesses.

JOHN MATHEUS.
